What Rex TK-2251 Klister is made of, ingredients and materials

Rex TK-2251 Klister is a hydrocarbon wax-based ski wax formulated for wet, icy snow conditions. Klister products are typically blends of mineral waxes, resins, and solvents designed to remain tacky at warmer temperatures where traditional hard waxes fail. The hydrocarbon base (as opposed to fluorocarbon or synthetic additives) means the product avoids certain classes of persistent additives, though volatile organic compounds (VOCs) are present during application.

What’s concerning

♾️

No PFAS disclosure

No public statement from the brand about PFAS in this product.

♾️

Category baseline

The starting point for this type of product, before anything specific to this product is counted.

90/ 100
⚠️

Volatile organic compounds (VOCs) during application

Hydrocarbon-wax klisters release solvents when warmed for application; prolonged exposure in poorly ventilated spaces may cause respiratory or neurological irritation. Rex does not publicly quantify VOC content, so individual batch composition is not verifiable.

70/ 100
⚠️

Ingestion risk (accidental or child)

Klister products are not food-grade and contain solvents and additives not intended for oral intake. While acute toxicity from small incidental ingestion is likely low, the product should be kept out of reach of children.

70/ 100

What’s reassuring

✅

Base material not linked to PFAS

The main material recorded for this product is not one associated with PFAS.

100/ 100
✅

Skin irritation or allergic contact dermatitis

No established cases of dermatitis linked to Rex TK-2251 or similar hydrocarbon klisters are documented. Resin components can theoretically irritate sensitive skin, but incidence appears negligible in this product class.

95/ 100
⛏️

Heavy metals

Mineral waxes used in ski products are typically refined to industrial purity and not known to harbor lead, cadmium, or arsenic. No third-party testing of Rex klister for trace metals is publicly available.

95/ 100
✅

Coating or residue adhesion to skin or equipment

Klister's tacky nature means residue adheres to skin and skis; this is by design and poses no direct toxicological hazard, though prolonged skin contact may increase irritation risk in sensitive individuals.

How is this PFAS grade calculated?

The brand's record and disclosure

Rex is a Norwegian ski wax manufacturer with decades of market presence and no known product recalls or safety violations on record. The brand does not publicly disclose detailed ingredient specifications or third-party safety certifications for this product line. No documented controversies regarding heavy metals, carcinogens, or allergens have been identified in available sources.

How it compares in its category

Rex klister occupies a conventional position in the ski wax market; comparable products (Rode, Swix, Toko) share similar hydrocarbon-wax architectures and present analogous hazard profiles. Klister products as a category carry lower chemical complexity than some performance additives in premium hard waxes. No evidence suggests Rex formulations deviate toward higher-risk additives relative to category norms.

If you buy it

Apply klister in well-ventilated spaces to minimize inhalation of volatile compounds released during warming and application. Store away from heat and direct sunlight to prevent degradation of the wax matrix. Wash hands after use to avoid skin contact with residues. Replace when the product becomes overly hard, separates, or loses tackiness, typically after one season of regular use.
