MS-920 Silicon Modified sealant
INTRODUCTION
MS-920 is a high performance, neutral single-component sealant based on MS polymer.It reacts with water to form an elastic material, and its tack free time and curing time are related to temperature and humidity.Increasing temperature and humidity can reduce tack free time and curing time, while low temperature and low humidity can also delay this process.
MS-920 has the comprehensive performance of elastic seal and adhesion.It is suitable for the parts that need elastic sealing in addition with certain adhesive strength.
MS-920 is odorless, solvent-free, isocyanate free and PVC free .It has good adhesion to many substances and does not require a primer, which is also suitable for spray-painted surface.This product has been proven to have excellent UV resistance, so it can be used both indoors and outdoors.
FEATURES
A) odorless
B) non-corrosive
C) good adhesion of a variety of substances without primer
D) good mechanical property
E) stable color, good UV resistance
F) environment-friendly -- no solvent, isocyanate, halogen, etc
G) can be painted
APPLICATION
A) Elastic adhesive of metal and plastic, such as car manufacturing in the side panel and roof, etc.
B) Elastomers, sealing of outdoor and indoor gaps and joints. Applicable to the following fields: vehicle body, train body manufacturing, ship manufacturing, container metal structure, electric equipment, , air conditioning and ventilation industries.
Ms-920L has good adhesion to most materials: such as aluminum (polished, anodized), brass, steel, stainless steel, glass, ABS, hard PVC and most thermoplastic materials. The film release agent on the plastic must be removed before adhesion.
Important note: PE, PP, PTFE does not stick to the relay, the material mentioned above is not recommended to test first.
The pretreatment substrate surface must be clean, dry and grease-free.

METHOD OF APPLICATION
The corresponding manual or pneumatic glue gun should be used for soft packaging, and it is recommended to control within 0.2-0.4mpa when pneumatic glue gun is used. Too low temperature will lead to increased viscosity, it is recommended to preheat sealants at room temperature before application.
COATING PERFORMANCE
Ms-920 can be painted, however, adaptability tests are recommended for a wide variety of paints.
STORAGE
Storage temperature: 5 ℃ to 30 ℃
Storage time: 9 months in the original packaging.
ATTENTION
It is recommended to read the material safety data sheet before application.See the MS-920 material safety data sheet for detailed security data.
