JOINT SEALANTS
WHY IS JOINT SEALING IMPORTANT? 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. Sika has a wide variety of joint sealant solutions that will suit all of your construction needs, browse our product lines to find which joint sealant is the solution for your next project!
JOINT SEALANTS
Proven over the years, JP FLOORING Polyurethane is the product of choice in a wide range of construction applications. Polyurethanes exhibit many characteristics that offer advantages in certain applications. These characteristics are:
ADHESION
JP FLOORING 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 JP FLOORING polyurethane sealants have superior wetting action in achieving a bond to various joint substrates under jobsite conditions.
SUBSTRATE STAINING
JP FLOORING polyurethane sealants possess an extremely stable consistency and will not stain or discolor virtually any common substrate.
WATER IMMERSION
Many JP FLOORING polyurethane sealants can be placed in totally immersed environments without being affected by the action of the water.
DIRT RESISTANCE
Because of their exclusive chemical design, JP FLOORING polyurethane sealants exhibit far less dust and dirt pick-up during cure and over the lifetime of the building.
PAINTABILITY
JP FLOORING polyurethane sealants can be treated with most coatings and paints without the risk of delamination.
SIKASIL SILICONE SEALANTS
Sikasil silicone sealants are the product of choice when specific characteristics are desired in a sealant. Typical conditions favoring the selection of Sikasil silicone sealants occur in glass-to-glass and glass-to-metal interface in glazing systems. Important characteristics include:
Adhesion
Excellent adhesion to glass including conditions subjecting the silicone sealant to reflected UV radiation at the bond line.
Color Retention
White and other light colors will not yellow with age, therefore the white silicone sealant will remain white.
Heat Resistance
Applications subjecting the silicone sealant to unusually high temperatures can often be sealed with Sikasil silicone sealant.
