Software ideas

1. The bonded floor need to be cleanse, dry and free of charge of putty just before bonding.

2. Substrates that could seep out of oil are not suited for direct application of sealant.

three. For rusted or corroded metal surfaces (such as aluminum oxide, copper, iron oxide rust area), in order to
guarantee the bonding impact, the rust on the floor layer demands to be worn off prior to coating.

4. Thanks to the building environment, design techniques, and materials variances, pre-testing is necessary before use to make sure adhesion performance.

5. The optimum coating temperature is +15 ~ +40°C. When the temperature is low, the extrusion resistance  will increase, heat up the adhesive before use.
