Silicone Resins (siblings)
MDT Silicone Resin
MDT silicone resins incorporate M (mono-functional), D (difunctional), and T (trifunctional) units, creating a branched network that combines M-unit tack with D-unit flexibility and T-unit crosslink density. MDT resins are the principal carrier resin in silicone pressure-sensitive adhesives alongside MQ, selected when greater peel strength and shear resistance are required.
Specifications
| Unit Composition | M + D + T (ratio tuned per application) |
| Peel Strength vs MQ | Higher at equivalent M content |
| Softening Point | 65–100 °C |
| Solid Content | 50–65% in toluene/xylene |
| Compatibility | PDMS gum, silicone rubber base polymer |
Applications
- High-peel-strength silicone PSA for industrial and medical tape
- Protective film for electronics and optical surfaces
- Double-coated silicone tape for thermal bonding
- Label stock requiring elevated shear resistance
- Silicone adhesive component in transdermal drug delivery patches
Key Features
- Higher peel strength than MQ at equivalent M content
- D-unit flexibility improves cold-temperature peel performance
- Tunable tack/cohesion balance via M:D:T ratio
- Compatible with platinum-cure PDMS systems
- FDA 21 CFR 175.300 grades available for food-contact applications
