Needle-punched nonwoven material is often used in filters. Rheology is an important property for the coating/binder as viscosity must allow good penetration and bond. Many filter applications also benefit from resistance to water as well as oil and other chemicals.
Rovene® 4021 is a good carboxylated styrene-butadiene latex for this type of application. Hydrophobic, and with some adhesion, it also provides a good combination of elasticity and strength.
Rovene 6014 is a self-crosslinking acrylic polymer emulsion providing a stiff hand to frothed or saturated substrates.
Rovene® 6017 is self-crossing linking styrene-acrylic emulsion polymer recommended for bonding nonwovens where a firm, durable binder is needed such as highloft webs, interlinings, and medical applications.
Rovene 4021 is a self-crosslinking, carboxylated styrene-butadiene emulsion that has a firm hand with outstanding strength properties. This latex is especially suited for various nonwoven, textile and performance coating applications.
Rovene 4201 is a self-crosslinking, carboxylated styrene-butadiene emulsion that has a stiff or ‘boardy’ hand. This binder is recommended for durable nonwovens such as floor maintenance pads and roof shingle mats, both glass and organic.
