J20 UV General Purpose Cure & Seal

Product: General Purpose Cure & Seal (J20 U.V.)


Description: General Purpose Cure & Seal (J20 U.V.) is an acrylic co-polymer cure, seal and dustproofing compound in an aromatic solvent containing 25% solids. It is designed for ease of application and better atomization when spraying in a wide temperature range from 35°F to 90°F (2°C to 32°C). J-20 U.V. will be ultraviolet stable and resist yellowing. The higher acrylic solids content will form an excellent surface coating with a high gloss finish that provides an outstanding cure performance.

Purpose: General Purpose Cure & Seal (J-20 U.V.) provides a combination of curing, sealing and dustproofing for freshly finished interior or exterior concrete surfaces. It meets ASTM C-309 specifications as an outstanding curing compound and is an excellent dustproofer and surface sealer. J-20 U.V. will resist many chemicals, help protect against staining and allows easy removal of mortar splatters.
