Book A Consultation

I started work for TECHSiL in 1998, as a Sales Director and joint owner. My career in the polymer industry began in 1976, as an apprentice polymer technologist for the Chloride group in Bolton. On completion of this, I was lucky enough to do a degree level qualification in the same discipline. My roles have involved technical, development, and troubleshooting in manufacturing, then into marketing and product management across general industry, aerospace/defence and into electronics.

Book A Consultation

I have been working within the adhesives industry for 25 years, and with TECHSiL for almost 2. Over the years I have worked within different companies from start-ups to multinationals and have been within many industries always being close to engineering, production and purchasing. The chemistry and challenges have kept me stuck to the industry, but my current focus is space, defence and aviation.

AEROSPACE SOLUTIONS BY APPLICATION

AVIONICS AND ELECTRONICS PROTECTION

Conformal coatings and protective silicones help reduce corrosion risk, tolerate mechanical stress, and provide stable insulation across wide temperatures.

Where higher voltages and long-term reliability are critical, dielectric silicone gels provide a stress-relieving electrical barrier and help reduce partial discharge risk through void-free encapsulation.

SEALING, COATING, POTTING AND ENCAPSULATION

Sealants in Aerospace are used for potting and encapsulation of sensitive electronics, bonding interior panels/windows/fixtures, sealing in extreme environments (including satellites), engine sealing, exterior thermal coatings and protection of optics, solar arrays and crew compartments.
Silicone RTVs are widely used because they remain flexible, offer vibration dampening and stress relief, and can provide insulation and dielectric properties around electronics as well as resistance to chemicals and fluids.

SPACE AND SATELLITE MATERIALS: LOW OUTGASSING SILICONES

In spacecraft, outgassed volatiles can cause serious reliability issues, so low outgassing silicones are used to minimise volatile content and meet relevant standards. Typical benefits include room temperature cure, UV and ozone resistance, thermal insulation, flexibility at very low temperatures, protection against corrosives / water / oils / salts, and meeting or exceeding ASTM E595. Potential applications include solar array and optical sealing, heat shielding, crew capsule uses, coatings for critical equipment, and encapsulation/potting for high heat locations.

TAPES FOR AEROSPACE: INTERIOR, EXTERIOR AND HIGH TEMPERATURE

TECHSiL supplies Aerospace tapes designed for bonding, sealing and insulation in demanding aviation environments.

For high-temperature and harsh processing environments, TECHSiL also supplies specialist high-temperature tape solutions, including products referenced for plasma spraying processes, and notes approvals by major engine and airframe names.

STRUCTURAL BONDING FOR LIGHTWEIGHTING AND JOINT INTEGRITY

Structural adhesives can replace or reduce mechanical fastening, distribute loads, and support mixed-substrate joining.

The Scotch-Weld guidance highlights epoxy strength and environmental resistance for long-life assemblies where high strength is mandatory.

CASTING, PROTOTYPING AND RAPID PART PRODUCTION

Casting materials are used in Aerospace for air ducting systems, electronic enclosures/housings, soft goods, rapid prototyping, repair parts, radomes and even drone parts/accessories.

Urethane casting is positioned as a route to lightweight, durable complex shapes, with speciality formulations such as flame-retardant and high-temperature grades.
