New/Old Concrete Adhesive SC-705 

Introduction

This product is used when placing concrete in contact with hardened concrete or overlaying 

new concrete on old concrete. If shrinkage and expansion are different when adhering new 

and old concrete, poor adhesion occurs. SC-705 has almost the same expansion coefficient 

and tensile strength as those of concrete, so this product reduces the separation considerably. 

Intended Use

- Placing concrete in contact with hardened concrete and overlaying new concrete

- Reinforcing the separated site of aggregate

- Floor surface iron adhesive

- Reinforcing the sunken area of concrete

Features

- Excellent adhesive strength even in wet condition

- Excellent water resistance, chemical resistance, and workability

- Available down to three degrees below zero in winter 

- No separation because the shrinkage and expansion are almost the same as those of concrete

Storage

- Store in a dry place at room temperature of 20℃ with the lid completely closed.
