Product Description

NV-MQ902 is a methyl MQ silicone resin with a three-dimensional, Si–O–based resin structure consisting of M [(CH3)3SiO1/2] and Q [SiO4/2] units.With an M/Q ratio of 1.0:1, NV-MQ902 provides a balance of film-forming properties, adhesion, hydrophobicity, thermal resistance, and release performance.

NV-MQ902 is suitable for selected silicone-based coating, protective, release, and other specialty formulations requiring durable film formation, water repellency, thermal resistance, and surface performance.

Key Benefits & Features

Thermal Resistance: Provides good thermal stability for silicone-based formulations exposed to elevated temperatures and demanding environmental conditions.

Film Formation & Durability: Forms durable films with a balance of hardness and flexibility, together with good resistance to aging and UV exposure.

Water Repellency: Provides excellent hydrophobicity and contributes to water repellency in silicone-based coatings and surface-treatment formulations.

Adhesion: Provides good adhesion and bonding contribution in selected silicone-based coating and sealing systems.

Release Performance: Provides release-modifying properties and durable film formation in selected silicone-based release formulations.

Formulation Versatility: Can be incorporated into solvent-based or solvent-free silicone formulations through controlled thermal incorporation or pre-dilution in compatible media.

Applications

High-Temperature & Electrical Insulation Coatings: Used in selected silicone-based high-temperature coatings, electrical insulation systems, and protective formulations, including applications for Class H electrical equipment.

Water-Repellent & Protective Coatings: Suitable for silicone-based waterproofing, water-repellent, and protective coating formulations requiring hydrophobicity and environmental resistance.

Release Formulations: Used as a film-forming and performance-modifying component in selected silicone-based release formulations for plastic, rubber, composite, and other molding applications.

Bonding & Sealing Formulations: Suitable for selected silicone-based bonding and sealing systems where adhesion, film formation, and thermal resistance are required.

Specialty Surface Treatments: May be incorporated into selected silicone-based surface-treatment formulations where water repellency, durability, and surface protection are desired.

Application Guide

Incorporation Methods

Direct Thermal Incorporation:For direct addition into solvent-free systems, NV-MQ902 should be heated under controlled conditions until sufficiently softened or fluidized before incorporation. Adequate agitation should be used to ensure uniform dispersion.

Solvent Dilution:For solvent-based systems, NV-MQ902 may be pre-dissolved or diluted in compatible solvents or silicone media prior to incorporation. Suitable media include D5, selected PDMS fluids, 120# solvent oil, toluene, and xylene.

Avoid localized overheating and prolonged exposure to excessive temperatures during processing.

Recommended Dosage

Typical dosage: 1–20 wt%, based on total formulation.

The optimum dosage depends on the application, base polymer, desired film properties, substrate, and other formulation components. Laboratory evaluation is recommended to determine the appropriate dosage for each specific application.
