Overview

This document serves as a comprehensive product selector guide for electro-chemical solutions, focusing on various types of conformal coatings, polyurethane and epoxy resins, silicone compounds, thermal management materials, lubricants, and cleaning agents. It provides detailed specifications, performance parameters, and application recommendations for each product category.

1. Single-Part Conformal Coatings

These coatings are designed for protection of electronic components with a variety of formulations including aromatic-free acrylic, modified alkyd, silicone, urethane, and UV cure types.

• Key Properties: Viscosity ranges from 150 to 550 mPa·s; solids content varies between 2% and 100%; dielectric strength ranges from 17 to 90 kV/mm; temperature operating ranges from -70°C to +200°C depending on product.
• Drying and Curing: Touch dry times vary from 5 to 55 minutes at 20°C; cure times typically 24 hours at 20°C, with some UV cure options offering faster curing.
• Resistance: Good solvent, humidity, and mold resistance; thinners specified per product.
• Approvals: Many products meet IPC-CC-830, UL746, IEC61086, MIL-I-46058C, and BMW GS95011-5 standards.

2. Two-Part Conformal Coatings

These coatings offer enhanced performance such as high temperature resistance, flame retardancy, abrasion resistance, and UV cure capabilities.

• Key Properties: All have 100% solids; viscosity is sprayable; dielectric strength consistently 90 kV/mm; temperature ranges from -65°C to +150°C.
• Curing: Typically cured at 80°C for 10 minutes; touch dry times around 240 minutes at 20°C, except UV cure which is faster.
• Approvals: Some meet BMW GS95011-5 and IPC-CC-830; UL94 V-0 flame retardancy achieved by select products.

3. Polyurethane and Epoxy Resins

These resins provide excellent adhesion, optical clarity, thermal conductivity, and chemical resistance for various applications.

• Properties: Mixed viscosities range from 100 to 30,000 mPa·s; cure times vary from 2 to 48 hours depending on temperature; thermal conductivity ranges from 0.20 to 1.54 W/m·K.
• Temperature Range: Operating temperatures from -70°C up to +210°C (short term max up to +245°C).
• Flame Retardancy: Some products achieve UL94 V-0 rating.
• Specialist Properties: Options include soft, low stress, water resistance, and UL approved formulations.

4. Silicone Compounds for Thermal Management

These compounds are designed for heat transfer applications with varying thermal conductivities and viscosities.

• Thermal Conductivity: Ranges from 0.90 to 3.40 W/m·K.
• Density: Between 2.10 and 3.10 g/ml.
• Temperature Range: -50°C to +230°C depending on product.
• Dielectric Strength: 12 to 42 kV/mm.
• Curing: RTV types require moisture to cure; others are ready to use.

5. Lubricants

Various lubricants are listed with properties tailored for electrical performance, plastic compatibility, and thermal management.

• Temperature Range: From -70°C to +300°C depending on product.
• Penetration and Drop Point: Penetration values around 280-330; drop points mostly at 200°C or higher.
• UV Trace and Oil Versions: Some lubricants have UV traceability and oil variants.

6. Thermal Management Materials

Includes thermal phase change materials, gap pads, and 2-part epoxy/polyurethane/silicone resins designed for heat dissipation.

• Thermal Conductivity: From 1.20 to 5.50 W/m·K.
• Temperature Range: -50°C to +200°C.
• Cure Times: Vary from 1 hour to 24 hours depending on material and temperature.

7. Cleaning Agents

Two categories: aqueous and solvent cleaning agents designed for removal of flux, grease, and other contaminants.

• Aqueous Cleaners: Various formulations with ultrasonic compatibility, pressure wash, spray under immersion, and stencil cleaning capabilities.
• Solvent Cleaners: Include hexane-free, lead-free flux removers, non-flammable solvents, and electronic cleaning solvents with flashpoints ranging from -48°C to >60°C.
• Properties: Density ranges from 0.78 to 1.33 g/ml; evaporation rates and vapor pressures vary widely.
