- Product Information
The company developed a waterproofing system based on moisture triggered chemistry. This system incorporates Incozol 4 which uses atmospheric moisture to trigger the curing process. This means the waterproofing membranes are capable of curing in a wide range of conditions without any subsequent loss of performance or durability. Soon after application the freshly applied membrane will show no adverse reaction to water. The addition of Incozol 4 promotes fast through-cure but without any CO2 gas evolution. It also allows the formulator to reduce the isocyanate level which could lead to a reduction in toxicity of the finished product.
- Product Highlights
- Incozol 4 is used in a wide variety of coating applications and is particularly advantageous where high build properties are desirable, for example, waterproof balcony coatings.
- In a traditional moisture cure reaction, moisture reacts directly with the terminal isocyanate of the prepolymer generating gaseous carbon dioxide. In a moisture triggered system, moisture reacts preferentially with the oxazolidine (Incozol 4) rather than with the prepolymer’s terminal isocyanate groups. This results in greater crosslinking (faster through-cure) but without the carbon dioxide gas evolution that would lead to bubbling, pinholing and downglossing.
- Incorporating Incozol 4 into the system also allows the formulator to reduce the isocyanate level and, therefore, the toxicity level without adversely affecting the cure rate. For example, a standard commercial aliphatic prepolymer with typically 15% NCO content can be significantly reduced to typically 3% NCO with the addition of Incozol 4.
- Enables the polyurethane coatings to be cured across a wide range of atmospheric conditions
- Faster through cure of the polyurethane coatings lead to increased tensile strength and tougher, more durable coatings
- Reduce usage in the polyurethane coating formulation
