HX-800 Latex is the pre-vulcanized form of HX-80. It was designed specifically for short run polyester work. When polyester resins are cast into natural Latex, a tackiness develops on the surface of the rubber and/or polyester cast. This is due to free sulfur not combining with the mold. The problem can be solved by using a pre-vulcanized Latex such as HX-800. Pre-vulcanized molding compounds contain no free sulfur on the surface and can therefore be used for short run polyester resin casting; avoiding the necessity of an aluminum or plaster separator during the curing process.
HX-800 is also an excellent cleaning aide for architecturally significant concrete. Simply brush on a few layers let dry, and peel. Dirt, and grime will pull away with the latex skin.
Allergies: Read label carefully. Do not use this product if you have known allergies to rubber latex. If you're unsure, bring the label to your doctor for their advice. If an allergic reaction occurs, stop use and seek medical help right away.
Have used this HX-660 many times and it always performs well.
