ORGAL®K 637X

Acrylic Polymer for Roof Coatings and Horizontal Mastic Applications

1/10

INTRODUCTION

Orgal K 637X is an APEO and formaldehyde free, low Tg pure acrylic polymer emulsion that forms a clear, elastic and slightly tacky film. Orgal K 637X shows excellent adhesion on challenging surfaces like rigid PU foam and bitumen membrane. The coatings formulated with Orgal K 637X show excellent resistance to isocyanate migration from PU foam and bitumen migration from the membrane. The films of Orgal K 637X show excellent flexibility and have high UV and water resistance.
