MG-Guard
MG-Guard UV-3039 is a liquid cyanoacrylate UV absorber that is especially compatible with common plasticizers, both phthalate and non-phthalate. A strong UV-B absorber, MG-Guard UV-3039 screens ultraviolet radiation and imparts colorfastness, protection against surface crazing, and retention of physical properties during ultraviolet exposure to a number of polymer systems, including TPU, PMMA, polyesters, and especially plasticized PVC. For CASE applications, MG-Guard UV-3039 is useful in silicone emulsions, inks, acrylic, vinyl, urea-formaldehyde, alkyd, epoxy, and polyurethane. Additionally, MG-Guard™ UV-3039 is a common absorber for sunscreens and other cosmetics. FEATURES & BENEFITS: Strong UV-B absorption for especially sensitive pigments or polymers; Low initial color; Liquid product form allows for ease of handling with plasticizers; Excellent synergy with hindered amine light stabilizers (HALS) in appropriate resin systems.

MG-Guard™ AO-725 is an oligomeric high molecular weight primary antioxidant originally designed for the rubber industry. Due to the fact that this antioxidant is not held together with hydrolyzable functionalities, it is an excellent choice in thermoplastic applications requiring high additive extraction resistance or especially aggressive thermal use cases. Key applications include underwater submersion robustness (especially for UL wire jacketing testing), TPO roofing membranes, and under-the-hood. MG AO-725 is compatible in a number of thermoplastics, including: polyolefins (PE, PP), rubber-modified polyolefins (TPO, TPV), polyamides, EVA, PVC, polycarbonate, polyesters (PET, PBT), styrenics (ABS, PC/ABS, PS, SAN, ASA), and adhesives, among others. Due to the reactive phenolic structure, this material is prone to phenolic yellowing, and is best suited for applications.
MG-Guard
MG-Guard FS-042 is an alkyl hydroxylamine antioxidant that does not contain any potential chromophores within its structure. When added to polyolefin resin during production, this material will not "gas fade" /turn pink or develop phenolic yellowing under any conditions. MG-Guard FS-042 is particularly useful for film and fiber applications in polypropylene, polyethylene, and TPO. Hydroxyamine antioxidants display a strong synergistic effect when used in combination with phosphite antioxidants, such as AO-168 and AO-626. Typical loadings for MG-Guard FS-042 range from 0.05% to 0.20%. FEATURES & BENEFITS: No "gas fading" / pinking or phenolic yellowing; Good antioxidant activity during polymer processing; Cosynergist for long-term heat aging (LTHA); Low propensity for yellowing/increases in b value from weathering/processing.

MG-Guard HAS-3529 is a high molecular weight tertiary hindered amine light stabilizer (HALS). This additive imparts excellent colorfastness and thermal stability to a number of polymer systems, including: polyolefins (PP, PE), rubber-modified polyolefins (TPO, TPV), polyamides, PMMA, styrenics (PS, ABS, SAN, ASA), polyacetals, PET, PBT, and PVC, among others.

MG-Guard LS-701 is a top-of-the-line synergistic mixture of absorbers and stabilizers, imparting outstanding stability against UV and thermal degradation for polyolefins and rubber-modified polyolefins (PE, PP, TPO). MG LS-701 is used when ultra-long-term performance is required; 10+ years outdoor stabilization is possible with modest loadings of this stabilizer. Typical loadings are in the 0.1-1.0% regime, depending on formulation specifics and desired service life. For extra protection against surface crazing/cracking, especially for PP and TPO, MG LS-701 demonstrates excellent synergism with low molecular weight HAS, including UV-3853.Features Benefits: Appearance: White to off-white powder; Outstanding UV stability compared to "common" packages, e.g. UV-791; Excellent long-term UV color stability and thermal stability; Resistant to deactivation from acids and halogenated flame retardants; Reduced mold deposits/minimal interactions with metal stearates; Excellent paintability, non-migratory/"blooming", non-fogging; FDA sanctioned in polyolefins (Additives 21 CFR 178.2010 / Olefins 21 CFR 177.1520)

MG-Guard UV-1 is a viscous liquid formamidine UV absorber that is especially effective at absorbing UV radiation between 300-325nm, where polyurethanes are especially sensitive. MG-Guard UV-1 is miscible with polyester polyol and polyether polyol and has good compatibility with isocyanates. This absorber imparts colorfastness, protection against surface crazing, and retention of physical properties during ultraviolet exposure to a number of systems, including polyurethanes (foam, semi-rigid, fabric coating), adhesives, sealants, and elastomers.
FEATURES & BENEFITS:
• Strong absorption between 300-325nm
• Low initial color
• Good compatibility with polyurethane ingredients, good solubility in common solvents
• Excellent synergy with hindered amine light stabilizers (HALS)
