Dysprosium material DM6639 high-strength UV pressure-sensitive adhesive replaces pur adhesive

DeepMaterial DM6639 high-strength UV pressure-sensitive adhesive replaces pur adhesive

Product Overview

DM-6639 is an acrylic adhesive system. After UV curing, it has a certain degree of pressure sensitivity. This formula is based on solvent-free modified acrylic ester, with a semi transparent colloid. The adhesive surface can be quickly cured in a few seconds, and after curing, it can be attached to another substrate. After a short period of pressure holding and a period of post curing, the mechanical properties reach the best, and the product can be used as a substitute for PUR. In addition, this adhesive can accept the compression of uneven substrates, fully cure to meet IP68 waterproof requirements, and heat to a certain temperature to damage the bonding area, thereby achieving the purpose of repair.

Instructions for using high-strength UV pressure-sensitive adhesive

This product is sensitive to light and air. During storage and use, exposure to the external environment and artificial light should be minimized as much as possible.

When dispensing this product, a black rubber hose and a needle with UV protection are required. To achieve optimal performance, all surfaces in contact with the material should be clean and free from solder residue, grease, release agents, or other contaminants before material distribution.

Excessive uncured glue can be wiped off with alcohol.

After the dispensing is completed, UV curing should be carried out as soon as possible. After UV curing, the adhesive substrate should be pressed and held for a short period of time to maintain the pressed state.

The curing speed depends on the intensity of the lamp and the distance from the light source.

Precautions for high-strength UV pressure-sensitive adhesive
