Penatron 4037

Product Description

Penatron 4037 is a softer and more flexible version of the 4036 low viscosity urethane/polyurea. The 4037 is specifically designed for the rapid applications of concrete sealing, annular filling for fixtures, filling expansion joints in concrete or asphalt, repair of cracks in asphalt pavement, asphalt to concrete joints, moving concrete joints and asphalt kerf installations where a product with lower durometer hardness is needed.
Penatron 4037 is designed for quick and machine applications for expansion joint applications. The product is black, has high chemical resistance and mixes easily as a 1:1 ratio mix using the ASTC Little Squirt application pump or a speed mixer and a drill motor. The product has an excellent bond to concrete and asphalt surfaces. Penatron 4037 applications can be put back in service in approximately 30-45 minutes after the installation is complete and the product is ready for pneumatic tire traffic.
Note: Environmental temperature plays a role in set time; environments with high heat will speed the set time of the product, cool temperature will slow the set time. 4037 may be supplied in the same set time as the 4036 as needed.

Unique Characteristics: 4037 is low in viscosity allowing the product to penetrate into the asphalt or concrete joint surfaces. Normally no priming is needed. Moist areas should use a primer. Applications are made quickly and set time is in about 4 to 6 minutes and can be adjusted for slow set as needed. Standard speed is fast set allows for a back-in-use time or approximately 30 to 45 minutes.
