AERAFIN Polyolefins and REGALITE Resins for Hot Melts

AERAFIN polymers are propylene-ethylene copolymers for hot melt adhesives, compatible with hydrocarbon tackifying resins. Grades target hygiene, packaging, automotive interiors, filters, mattresses and wood working. Hydrogenated REGALITE R1090 and R1100 resins tackify EVA and SIS hot melts.

AERAFIN 17 and 180: spraying from 130 °C
AERAFIN 230: RBSP below 160 °C
AERAFIN 85: adhesion to low energy substrates
REGALITE C6100SD: for SIS, SEBS and SBS

LITHENE Liquid Polybutadiene for Sealants and Rubber

LITHENE products are 100% active liquid polybutadienes in a range of molecular weights and micro-structures. They serve sulphur or peroxide cured automotive sealants and adhesives, rubber coagents and electrical encapsulating resins. Maleic anhydride grades enhance adhesion direct to metals.

ULTRA AL-15MA: 15 parts maleic anhydride
ULTRA PM4-7.5MA: 7.5 parts anhydride
ActiV 1000: Type II coagent
ULTRA PH: coagent in EPDM rubber

Binders for Sealants, Labelling and Contact Adhesives

PLEXTOL A 412AF and REVACRYL AE 4625 are compounding bases for construction sealants. Styrene-butadiene LITEX A 2331, A 61H and S 61 go into can sealant compounds. PLEXTOL A 1819 is a base for wet glues in paper onto glass bottle labeling, and A 1732 replaces chloroprene in 2K contact adhesives.

A 412AF: low water uptake
AE 4625: ammonia- and formaldehyde-free
A 1819: alkali-soluble acrylic binder
A 1732: chloroprene replacement

AXILAT, LIPATON and REVACRYL Polymers for Tile Adhesives

For EN 12004 tile adhesives the range includes AXILAT redispersible powders, LIPATON styrene-butadiene and REVACRYL styrene acrylic dispersions. All polymers are solvent-free, low-odour and low-VOC. PLEXTOL E 307 is an ammonia-free high solids acrylic dispersion for flooring adhesives.

AXILAT PSB 155: one-tenth particle size
REVACRYL AE 3723: VOC below 300 ppm
LIPATON SB 29Y141: industrial screeds
PLEXTOL E 307: flooring adhesives

Acrylic and Vinyl Acetate Binders for Paints

Binders for interior and exterior paints include PLEXTOL pure acrylics, REVACRYL styrene acrylates and EMULTEX vinyl acetate copolymers, all APEO-free. Low MFFT PLEXTOL D 471 and D 498 serve exterior masonry paints and renders, and P 7730 elastomeric wall and roof coatings.

EMULTEX VV 665 BIO: 20% bio-origin
PLEXTOL D 498: silicate coatings
PLEXTOL P 7730: elastomeric coatings
EMULTEX P 7215: plasticizer-free

Choosing a PSA Dispersion by Label Type

The PLEXTOL grade is chosen by the label service conditions.

For freezer labels the manufacturer lists A 4803 with tack at very low temperatures, for cold and moist surfaces of chilled goods A 1777, for filmic labels with high water resistance A 4805, and for labels with constant adhesion and clean removability A 4064.

A 2861 S with high cohesion and strong adhesion to PVC is recommended for automotive tapes, battery wrap tapes and specialty labels, and A 7703 for clear-on-clear labels optimised for gravure coating.

Where the pack goes to recycling, RECYCLEAR 2529 serves wash-off labels on PET bottles and RECYCLEAR 3141 filmic labels on HDPE rigids.

Matching a TACOLYN Resin to the Base Polymer

A TACOLYN dispersion is matched to the latex it modifies. TACOLYN 1070 (55% solids) is recommended for acrylic latexes in label, tape and construction adhesives and enhances adhesion to polyolefin substrates and recycled corrugated board.

TACOLYN 5002 serves natural rubber and SBR latexes, while TACOLYN 5085, based on an aliphatic C5 resin, tackifies isoprene and natural rubber latexes in tapes.

For anionic polychloroprene contact adhesives a single tackifier is used without a second reinforcing resin: TACOLYN 5003 (45%) or its low odor, DPOS-free version TACOLYN 5014 (40%). TACOLYN 3400, a highly hydrogenated rosin ester, targets food packaging and high temperature masking tapes.

Choosing an AERAFIN Grade by Hot Melt Application

The manufacturer finder lists AERAFIN 17 and 180 for assembly, 85 and 230 for automotive and filters, 20 and 85 for end-of-line packaging, 17, 37, 75H and 180 for hygiene, 35 for insulating glass, 35 and 180 for mattresses, 75H for general packaging and 85 for wood working.

Formulations based on AERAFIN 17, 75H and 180 spray at temperatures as low as 130 °C, and AERAFIN 230 combines high temperature resistance with a ring and ball softening point below 160 °C. In polyurethane hot melts for wood working, amorphous polyolefins improve green strength, and open and set times are tuned by dosage.

Polymers for Tile Adhesives and Screeds

For cementitious tile adhesives the manufacturer gives formulations on AXILAT 460S, LIPATON SB 40Y45 and AXILAT 8530, for low carbon cement adhesives on AXILAT PSB 155, and for paste adhesives on REVACRYL L 8761 and REVACRYL AE 4522.

AXILAT PSB 155 redisperses to a particle size one-tenth of conventional latex powders and suits cement- and gypsum-based applications. AXILAT UP 465S reaches EMICODE EC1+ classification due to its very high alkaline resistance.

LIPATON SB 29Y141 is designed for industrial flooring screeds, and REVACRYL AE 3723 has a VOC content below 300 ppm. The polymer is selected for EN 12004 slip resistance, open time and deformability.
