The two-Component Field

Since Dr. Bayer invented polyurethane (PU) foam in 1936, two-component reactive liquid systems have become a major aspect of everyday industrial production. Apart from PU foams and their derivative elastomers, reactive chemical systems now include epoxies, acrylics, silicones, polysulphides and polyesters. Their uses, in terms of bead, shot of dot application, include bonding, sealing, structural composite fabricating, encapsulating, impregnating, coating, moulding, mould making and rapid prototyping through to electrical, thermal and fire insulating,

Processing the two-component reactive liquid systems involves the accurate metering of both liquids in ratio to each other prior to their being mixed together. Ratios are by weight or volume and usually range from 1:1 to 10:1 according to their individual specification. After mixing, resins may also require dispensing in a specific metered volume or at specific metered rate.

Over the last 30 years or so, and as a result of a dramatic increase in their use, it became vital to develop ways to simplify their packaging, storage, handling and the final metering, mixing and dispensing process. The following are now key to this requirement.

Cartridge Systems

These are normally purchased by the chemical companies who specialise in the packaged supply of two-componants systems and who need to package their products in user friendly and reliable meter-mix-dispense devices. Sulzer Mixpac side by side cartridge systems are accurate, reliable and ideal for low volume use. A cartridge system includes the cartridge and its components, static mixer and the relevant manual or pneumatic dispenser/gun.

Machine Mixers (Disposable and non-disposable)

Sulzer Mixpac has a broad range of static disposable mixers, (plastic) and non disposable mixers (st.st.). There are also rotary mixers (plastic) where high shear mixing is required.

DX Machine

The DX is a simple, mass produced, low cost, yet all round performance machine in hand held, stand mounted, robot mounted and backpack versions.

DX Recharging From Drums

Sulzer Metix Ltd has developed a range of equipment for recharging DX containers from drums.
