Product Details
Product Introduction
Polyurethane Foam Caulk is a one-component, moisture-curing, multi-purpose polyurethane foam filler and sealant. Its cured foam elastomer has excellent properties such as bonding, waterproofing, resistance to thermal expansion and contraction, heat insulation, sound insulation and even flame retardant (flame retardant only). It is suitable for gap filling, crack and fracture sealing. Normal use temperature is 5-35℃, the best use temperature is 18-25℃.

Excessive addition of chlorinated paraffin increases the oiliness of the product and emits harmful gases.
|
|
Chlorinated paraffin: regulates product elasticity
|
Causes the product to be oily, reduces the adhesion of the PU foam, and can seriously lead to shedding.

|
Polyurethane copolymer: the main material of PU foam, affecting product quality, hardness adhesion
|
Stone powder increases the weight of the product, but does nothing for the product, resulting in lower gum yield.
