Resulting Properties
The formulation Waterborne Vinyl Acetate Ethylene High Quality Caulks (-17°C Caulk) will meet ASTM C834 Specifications for Latex Sealants. Testing includes extrudability after aging, weathering, volume shrinkage, extension recovery, adhesion, stain resistance and tack free time. These adhesive formulations have excellent low temperature flexibility and good aging characteristics. They have excellent adhesive properties for some of the more difficult to bond substrates used in the construction fields. The formulations also provide excellent toughness, flexibility, and durability.
