Introduction:
MF212 is a single component, neutral cure, high flexibility, high modulus silicone sealant, has excellent oil resistance, electrical insulation, water resistance and resistance to high and low temperature performance.
Features:
High flexibility, high modulus neutral curing, no corrosion on all surfaces.
It has good resistance to high temperature performance and excellent oil resistance.
Good electrical insulation properties on environmental pollution.
Purposes:
1. The engine block used in cars, motorcycles, etc., oil pan, transmission, etc. combined face and flange sealing surface;
2. Applicable to the joint surface of hydraulic machinery equipment such as pumps, fuel pumps, hydraulic pumps, air compressors and other required sealing;
3. The rubber pads can replace a variety of restrictions, on the edge of asbestos mats and other vehicles, motorcycles and all kinds of machinery and equipment engines, gearboxes and other parts of the implementation of joint surface sealing, free from the size and shape of the joint surface.
Instructions:
1. Can be directly extruded at 10 ºC ~ 50 ºC conditions.
2. To ensure that the sealant has good adhesion, bonding surfaces must be wiped off the moisture, grease, dirt, etc., to ensure that all sticky surface clean, dry and free of dirt.
3. To ensure that the sealant does not pollute the surrounding construction joints, surface protection tape must be used to protect, when dispensing is completed, it is removed.
4. After use, if there are still remaining glue, need air exhaust pipe, and tighten the lid to facilitate the next use.limit
Restrictions:
1. This product does not apply to the following situations:
2. Leaking grease, plasticizers or solvents.
