PU / Polyurethane Sealant

Polyurethane sealant (PU sealant) is a sealant with polyurethane rubber and polyurethane prepolymer as the main components.

This type of sealant has high tensile strength, excellent elasticity, abrasion resistance, oil resistance, and cold resistance, but it has poor water resistance, especially alkali resistance. It can be divided into heating vulcanization type, room temperature vulcanization type, and hot-melt type. Among them, the room temperature vulcanization type is divided into one-component and two-component.

 

It is widely used as a caulking sealing material in buildings, squares, and highways, as well as sealing in automobile manufacturing, glass installation, electronic filling, submarines, and rockets.

Sheet Metal / Auto body Sealant

 

Metal Sheet Sealant,  on the market, there are many of which are designed to be used with specific metal types. Here are the most commonly used sealants for metals and the metal types to which they should be applied.

 

Silicone Sealant :

The most widely used, and most versatile sealant to use for metals is silicone. Silicone Sealant is a high-performance, excellent waterproof sealant for repairing and sealing sheds, siding, gutters, recreational vehicles, roofs, and vents.  Silicone has many uses for sealing many types of metal structures and substrates. It is used on metal roofs, window installation, marine structures, and plumbing applications. The various metals it can be applied to are iron, copper, aluminum, steel, stainless steel, and galvanized steel.

Polyurethane Sealant

Polyurethane Sealant is a very common type of metal sealant. It comes in both a semi-solid form for sealing joints and in a liquid form for sealing large surfaces of metal.

MS Sealant ( Modified Polymer Sealant)

MS is an elastomeric sealant used for various surfaces and architectural metals. It is with the advantage of Silicone and Polyurethane, with good bonding & Sealing property, excellent waterproofing, UV resistance, easy to apply, can be painted.

 

Here, we say the sheet metal sealant, we mainly use for the Auto body, bus body, bus roof. We also call auto body sealant, bus body sealant.

 

For Maxtech company,  PU sealant, we have PU813, PU812, and PU814 can be used for metal sheet bonding and sealing. the application as the pictures:

Construction Industry Sealant

 

Construction industry PU sealant, we also called Polyurethane construction sealant, polyurethane sealant, non-staining polyurethane sealant, UV resistant PU sealant, etc.

PU Sealant is a one-part, elastomer sealant based on urethane which cures at room temperature. Maxtech has the self-leveling PU sealant and pastes state PU sealant.

Polyurethane Sealant is mainly used in applications relating to assembling and sealing. It is mainly used for sealing, filling gaps, keeping water and air away from joints, absorbing the natural movements of building materials, and increasing aesthetics. For these applications, the product is referred to as adhesive sealant or polyurethane adhesive sealant.

MAXTECH Provide Polyurethane Joint Sealants & Polyurethane Bonding Adhesive for Construction.

Polyurethane Joint Sealant

Polyurethane Joint sealant,  urethane construction joint sealant,  It is a wide range of construction applications, mainly for Sealing Purposes, sometimes we also say the General Purpose Sealants, Polyurethane construction sealant, polyurethane sealant, non-staining polyurethane sealant, UV resistant PU sealant, bubble-free polyurethane sealant. It is one component multi-purpose PU urethane sealants for use in expansion and control joints in pre-cast panels, and repair cracks or fills joints in horizontal or vertical concrete surfaces, tilt-up walls, metal curtain walls, window and door perimeters, and glazing details.

FOR MAXTECH, The polyurethane joint sealant, we have two types: Self-leveling joint sealant and Paste state joint sealant.
