Fill it! Fillers are dry materials that are compatible with Alumilite Polyurethane Resins. Fillers thicken and expand the volume of the casting plastic. It is best to not fill over 100% by volume, eliminating the chance of compromising physical...
The best and safest way to dispose left over resin is to mix the components A & B together, allow it to fully cure, and then dispose it in your garbage. Once the resin completely cures, it is an inert piece of plastic that can be discarded.
Alumilite has some very good adhesion qualities and wants to bond to anything it comes in contact with ... even when you don't want it to. It is best to try and clean liquid resin spill while they are still in the liquid form prior to them curing....
Pot Life or Work Time is the amount of time you have after two components have been mixed together before your chemical reaction starts to occur and your compounds will begin to set. Demold Time is the time you have to wait after it is solid...
Durometer refers to hardnerss, how hard or how soft a material is. Shore 'D' durometer refers to hard materials and surfaces such as the rigid resins. Softer materials are rated on the Shore 'A' scale. The higher the number, the harder it is. How...
Viscosity...Viscosity tells you how thick or thin a liquid is. The higher the viscosity number the thicker the liquid. The lower or close the number is to zero, the thinner the material will be. To give you a frame of reference, water has a...
1 year is the standard shelf life in unopened containers/bottles. However, as long as the resin has been kept free from moisture, it may still be good to use for much longer periods of time. Resin that has been as old as 4 and 5 years old works...
No. It is not required but is highly recommended to achieve castings with absolutely no air bubbles present within the cast piece as well as provide the best physical properties. Both of these materials start out at a higher viscosity (thicker)...
Amazing Clear Cast contains no VOCs and it's a 100% solids. Most epoxies smell and have a slight amine smell. The older the resin becomes, typically the stronger the material will begin to smell.
What prolonged exposure to high heat will do is soften the resin, whereas you could take your fingernail and make an indentation in the coating. Iit's also very important that the resin be mixed accurately and cured fully to achieve the max heat...
Yes, once cured, Alumilite resins can come in to contact or be submerged in water. Many users actually use our resin to cast custom fishing lures.
Unlike many of Alumilite's other resins, Alumilite Clear and Slow Clear need need to be mixed in a 1:1 ratio by weight. Tips that will also help it cure are pre-heating your mold (120-130F) to help facilitate the cure of the resin. Additionally,...
In most instances, we find that users are mixing Performance 65 & 80 by weight rather than by volume. The proper mix ratio is 1:1 by VOLUME. Mixing by weight can cause soft and sticky castings. Pre-heating your mold (120-130F) is always a good...
Any of Alumilite's rigid resins can be machined, sanded, and tapped. For turning applications we recommend Alumilite Clear and Slow Clear. When pouring blanks for turning applications, we do recommend pressure casting your pour to ensure there are...
Alumilite has a number of FDA compliant resins. All of which are epoxies. Amazing Clear Cast, Amazing Clear Cast Plus, Amazing Quick Coat, and Amazing Deep Pour are compliant when accurately measured, thoroughly mixed, and fully cured. Also, all...
Mild agitation by rotation of the unopended bottle will dislodged it but it returns after only a few minutes of standing. The best way to get rid of it permanently is to strain the chunks out. You can also simply not pour them into the measuring...
Alumilite resins will have some insulative properties but not as much as our silicones. Silicones will give you much more thermal and electrical insulation than urethanes however Alumilite resins will still act as a mild thermal insulator. It has...
All epoxies, no matter the make or the brand will yellow over time. Some formulations are formulated with UV absorbers and built in UV resistance that helps those epoxies retain their original color longer. But in the end, they will all turn...
Yes, Alumilite resins will have some insulative properties but not as much as our silicones. Silicones will give you much more thermal insulation than urethanes however Alumilite resins will still act as a mild insulator. So much that the...
Full cure on almost all of our materials is 72 hours even though over 90% of your physical properties will usually be obtained within 6-8 hours. This is very much part dependent though. Size, thickness, and overall part dimensions can play a role...
Yes they can be dyed using the same dyes as you use for the rigid resins. The dye will go in the A side of the Flex, stirred and suspened in the A side before combining the A and B. It is best to dye the Flexible series on an as needed/used basis....
The A side and the B side of the Flex are both very sensitive to moisture. Please store in cool dry area... however when it is time to use again it may have gelled the B side because of the cooler storage temperature. Yes it is still useable. You...
Technical term for thickness/thinness of fluids is viscosity. Viscosity is the measurement of the fluid's internal resistance to flow, this is normally designated in units of centipoise (cps). Put simply, the less viscous the fluid is, the greater...
First and foremost, the clear castings should be post cured well with heat. Otherwise the resin may be to soft to get satisfactory results. Unless there is parting lines or a matte finish, you do not have to wet sand. If sanding is required, start...
Bonding something to Alumilite works best when the material is still curing or shortly after demolding. The best adhesives for bonding Alumilite are ones that promote a chemical bond. Adhesives that work include but are not limited to: MMAS,...
Bonding Alumilite to itself is best when the material is still curing or while it it is still warm. If the Alumilite has cooled down, make sure you have a clean surface and lightly score or/sand in order to give it some bite for better adhesion.
The Clears are both optically clear and cure to rigid clear castings. However, the Alumilite Clear was developed specifically for applications where a higher durometer and better polishability is required. Therefore, the biggest difference between...
Not in order for it to cure but yes in order for it to cure with absolutely no air bubbles present within the cast piece as well as the best physical properties. Both of these materials start out at a higher viscosity (thicker) than the lower...
Yes! Alumilites low viscosity is ideal for picking up the detail required in thin walled rotational molded pieces. The hollow center will cut cost dramatically by reducing the amount of material that is required to cast your part. Sometimes it is...
Yes! Alumilite casting plastics work extremely well in a spin casting machine. Although spin casting was originated for low melt metals, you can get excellent castings with Alumilite resins. This technique allows you to produce many parts in a...
Yes! We recommend lacquers or acrylics but you may also use synthetics or enamels. A lacquer primer may be needed to assure the long tem effectiveness of the paint. You may wish to paint your silicone mold before casting Alumilite. Paint the mold...
To find the exact Heat Deflection Temperature or Heat Resistance of an Alumilite product, please see the individual product's technical data sheet (TDS). Alumilite resins will typically not melt but will eventually burn when exposed to extremely...
For fast setting resins, mix thoroughly for 30 seconds, being sure to scrape the sides and the bottom of your container. It should be mixed until absolutely no swirls or striations are visible. For resins with at least 5 minutes of open time, mix...
Alumilite opaque and clear resins will yellow over time if it is exposed to UV light. Clear acrylics or lacquers work well for protecting the resins from changing color. There are two ways of applying paint to achieve the best adhesion. First...
Yes. Alumilite offers a full line of dyes specially formulated for Alumilite's casting plastics and resins.. If you use an outside source of colorant or additive, make sure that the dyes/pigments are not water based. Water creates air bubbles...
Yes. Epoxies and urethanes are exothermic meaning they generate heat when they cure. The shorter the work time and faster the cure time, typcially the hotter or more heat they will generate. To extend the working time you can chill the A side, B...
This depends on the mass you are pouring, but typically ranges between 120°F to 200°F.
No. Varying the ratios will not affect the working time but it will affect the cure time and physical properties. Meaning, Alumilite will still start to set up in it's normal time but could take hours to completely cure. When it finally does cure,...
If you are casting a part in an open or one piece mold, pour slowly from one corner of the mold and let the material flow naturally to fill the mold. If it is possible, run the material down one side of the mold. If the mold has an undercut or...
Yes, it can be used to wet out fiberglass and other glass mattes to form structurally reinforced pieces.
