Kemko® 189 Polyurea SWL
Fast Set Elastomer for Control Joints and Spall Repair
Description
KEMKO® 189 Polyurea Sealant and Binder is a two-component, sag resistant, elastomeric polyurea sealant or binder designed for interior and exterior use. KEMKO® 189 is for filling non-structural cracks, saw cut slots, and control joints in concrete slabs. As a sealant (without aggregate), it meets ASTM C920 Type M (multicomponent sealant), Grade P (pourable or self-leveling sealant), Class 100/50 (adhesion/cyclic movement - withstand increases of 100% and decreases of 50% of the joint width), and use T1 (pedestrian and vehicular traffic). Per ACI 504 Guide to Sealing Joints in Concrete control joints are tooled or saw cut at a minimum depth of one quarter of thickness of the concrete slab are typically filled to full depth for load bearing applications. It is slighty overpoured to allow the elastomer to be trimmed flush with the concrete surface with a razor knife prior to full cure. KEMKO® 189 as a binder, is blended with aggregates and creates polyurea mortars, which can be used for rebuilding damaged joint nosing, repairing spalled concrete, and deteriorated concrete. KEMKO® 189 as a sealant or mortar has excellent resistance to vehicular tire impact and abrasion. It is resistant to most vehicular and aircraft fluids, as well as pavement deicing chemicals and free-thaw cycling
- Meets ASTM C920 Standard Specification for Elastomeric Joint Sealants (Type M, Grade P, Class 100/50, Use T1)
- Meets ACI 302.1R Guide for Concrete Floor and Slab Construction
Features
Unlike other elastomeric polyurea binders, Kemko® 132 does not embrittle nor degrade when exposed to sunlight for long periods of time and is environmentally safe. The product has a convenient 1:1 (by vol.) mixing ratio and a fast cure cycle for short downtimes. Kemko® 132 is formulated for balanced elasticity and toughness and is freeze-thaw resistant. The components do not contain volatile solvents (VOC’s).
