SEPNA Fast Cure one-component permatex high temp sealant for sealing waterproof, dustproof and anti-corrosion of vehicle body
 

S857 is also well suited for sealing applications on E-coated metals before subsequent paint processes (including powder coating processes).

S857  is designed as an adhesive/sealant. As an adhesive, it is usually used in combination with spot welding, riveting, clinching, and other mechanical fastening techniques to fix the parts until the curing process is completed. Bonding of oily substrates is possible up to an oil amount of 3 g/m2.

This product is suitable for professional experienced users only.
Tests with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.

 

S857 is a one-component solvent-free heat-curing sealant based on PVC/ Acylate.

 

S857 is cured by heat Curing depends both on temperature and elapsed time.
 

The most suitable heat sources are convection ovens.

 

The minimum heating temperature is 175°C (347°F), while

the maximum temperature must not exceed 230°C (446°F). It is

mandatory to perform tests with original parts to ensure proper

curing and function of the bonded part under original conditions

Product Advantages

S857 
 

230ºC/446ºF 

Heat curing

 

High-temperature resistance of

 

(180-230°C/356-446ºF),

no aging and discoloration

 

 

Suitable for powder-coating processes

 

 

 

Adheres well to most E-coated substrates and oily metal substrates.
 

 

Eco-friendly, PVC-free

 

Good tooling properties

Typical Applications

 

 

Suitable for powder-coating processes Matching powder paint

S857 is often used by paint and powder companies when preparing aluminium panels for automotive, construction and manufacturing industries in general. Panels can be bonded together with this adhesive more quickly than using traditional methods. Stainless steel stiffeners can be confidently bonded to panels prior to paint cycles within the cladding and commercial facade industry.

 

1. Used for clean metal or electro coat before powder coat.

2. For bonding clean the steel plate.

3. For bonding clean electrophoresis plates.

4. For sealing welds in the body.

5. For sealing welds outside the body.

6. It is used for sealing, waterproofing, dustproofing, and anti-corrosion of the vehicle body.

Application Process

 

Cure Mechanism

S857 is cured by heat. Curing depends both on temperature and elapsed time. The most suitable heat sources are convection ovens. The minimum heating temperature is 180°C (356°F), while the maximum temperature must not exceed 230°C (446°F). It is mandatory to perform tests with original parts to ensure proper curing and function of the bonded part under original conditions. For further information contact the Technical Service Department of SEPNA Industry.

 

Method of Application

To obtain the best strength, the following curing conditions should be followed: >175ºC(347°F)*30 min. Different curing conditions will lead to changes in shear strength.

 

Unpacks: S857 can be applied with electric or pneumatic-driven piston-operated guns. Drums: Dispensing from drums requires the use of standard hydraulic or pneumatic drive pumping equipment. For advice on selecting and setting up a suitable pump system, contact the System Engineering Department of the SEPNA Industry.
