Are Polyurethane Sealants The Best Choice for Concrete Joint Sealing?-TENGYU CHEMICAL (LONGKOU) CO., LTD

The joint is where the different building elements and materials meet. A joint is where two components meet and occur mainly within segments of construction or at a part of an interface between two variants. Joint sealing facilitates construction as many components are made of different materials that need a joint to allow for movement of the structure but must keep water, air, heat cold and vapor-tight seal. As the most vulnerable part of a structure, the joint needs the best product to protect the structure from the environmental elements and only correctly specified and professionally applied high-quality joint sealants will manage to keep the building or structure sustainably airtight during its lifespan.

Polyurethanes exhibit many characteristics that offer advantages in certain applications.

ADHESION

Polyurethane sealants will bond to more surfaces, particularly porous substrates such as concrete and masonry, without the use of a primer. It is an accepted fact that polyurethane sealants have superior wetting action in achieving a bond to various joint substrates under jobsite conditions.

SUBSTRATE STAINING

Polyurethane sealants possess an extremely stable consistency and will not stain or discolor virtually any common substrate.

DIRT RESISTANCE

Because of their exclusive chemical design, polyurethane sealants exhibit far less dust and dirt pick-up during cure and over the lifetime of the building.

PAINTABILITY

Polyurethane sealants can be treated with most coatings and paints without the risk of delamination.
