CRL Super Spacer Sealant

The CRL 877 Super Spacer Sealant is a single-component urethane formulation designed for the fabrication of high-quality, single-seal insulating glass units. This low-solvent formulation is compatible with the adsorbent of the Super Spacer, eliminating the need for a polyisobutylene primary seal.

The sealant can also be used with adsorbent-filled aluminum spacers, making it a versatile choice for the assembly of insulating glass units. The recommended temperature range for using the sealant is above 40°F (5°C), with a humidity level of more than 40%. The tack-free time is between 45-60 minutes at 77°F (25°C), and the cure time is 3/16 inch (4.76 millimeters) per 24 hours.

One of the key features of the CRL 877 Super Spacer Sealant is its compatibility with the Super Spacer adsorbent. This allows for a simple and cost-effective way to create high-quality insulating glass units, even in low-production environments. Simply attach a SGT Nozzle that matches the width of the Super Spacer and backfill the sealant to the edge of the glass.

The low-solvent formulation of the CRL 877 Super Spacer Sealant makes it an environmentally-friendly choice, as it reduces the amount of volatile organic compounds (VOCs) released during the manufacturing process. This makes it a suitable option for fabricators who are looking to reduce their environmental impact while maintaining the quality of their insulating glass units.

The minimum order for the CRL 877 Super Spacer Sealant is 1 Each, making it accessible to a wide range of fabricators, from small-scale operations to larger manufacturers. The compact 10.3 fl oz (305 ml) cartridge size also makes it easy to store and transport, ensuring a convenient and efficient application process.

It is important to note that insulating glass units should be fully sealed with the CRL 877 Super Spacer Sealant within one hour of exposing the Super Spacer adsorbent to the atmosphere. This ensures the integrity and performance of the sealant, and prevents any potential issues that may arise from prolonged exposure to the environment.

In summary, the CRL 877 Super Spacer Sealant is a versatile, low-solvent, single-component urethane formulation that is compatible with the Super Spacer adsorbent. It offers an easy and inexpensive way to create high-quality insulating glass units, even in low-production environments, while also reducing the environmental impact of the manufacturing process.
