Features & Advantages                    

lBright black, Clear, white, grey, impervious to oil.

lGood resistance to UV light and cold and hot weather alternation.

lExcellent anti-sagging property, low shrinkage after curing, good shaping, no dents, smooth coating.

lIt can be used for bonding and sealing in professional construction or decoration area. Good adhesion to many building materials.

lGood weather resistance.

lNo primer required.

Typical applications

DS-789 is suitable for elastic sealing of various substrate joints, including stainless steel, aluminum, copper, PVC, polyester, ceramics, wood, coating, etc. It can be used for outdoor general sealing in the construction area.

Application area

lBonding and sealing in the construction industry.

lExpansion joints.

lSealing and waterproofing of engineering and pavement gaps.

Application tips

lThe bonded surface must be clean, dry and free of putty before bonding.

lSubstrates that may seep out of oil are not suitable for direct application of sealant.

lFor rusted or corroded metal surfaces (such as aluminum oxide, copper, iron oxide rust surface), in order to ensure the bonding effect, the rust on the surface layer needs to be worn off before coating.

lDue to the construction environment, construction methods, and material differences, pre-testing is required before use to ensure adhesion performance.

lThe optimal coating temperature is +15 ~ +40°C. When the temperature is low, the extrusion resistance increases, warm up the adhesive before use.
