EZ-Blox® optimizes the performance of alkyd-based paint and coating systems by preventing a surface skin from forming on top when it comes into contact with atmospheric oxygen, for example, when containers are opened after use. Produced at our Hopewell, Virginia manufacturing plant, this breakthrough product offers equivalent efficacy and compatibility as the highest standard MEKO, thus providing a safe, cost effective and proven drop-in replacement for MEKO. With REACH-certification and a distinct, low-toxicity profile, EZ-Blox® is the ideal solution for paints and coatings producers looking to reformulate their high performance alkyd-based systems ahead of the ECHA 's March 1, 2022 reclassification and labelling requirements.

Performance Highlights

EZ-Blox® anti-skinning agent has a distinct, low-toxicity profile, and can be used as a drop in replacement for MEKO. These and other qualities described below are particularly important to European customers who need to address, in advance, the proposed recategorisation of MEKO with a reliable, proven and easy-to-convert solution.

EZ-Blox® Performance Overview

Benefits Characteristics Details
Safe To Use Low Worker Exposure Comfortably meets strictest German OEL1 standards, with a risk profile up to 100 times safer than MEKO3 .
Low Toxicology Profile
  • Not a skin sensitiser
  • No acute hazard concerns
  • Not genotoxic in animals
  • DNEL1 is at least twenty-five times higher than MEKO therefore, EZ-Blox® anti-skinning agent is safer than MEKO
  • Presently, the sole REACH registrant worldwide
No Cancer-Causing Potential in Liver As determined from toxicogenomic analysis
Favourable Results Extensive body of independent research and testing demonstrates EZ-Blox® anti-skinning agent has a distinct, low-toxicology profile.
Cost Effective Easy Switchover Paint producers have no need for costly reformulations or extensive research and development work.
Flexible Enables dosage flexibility similar to MEKO, resulting in low operational costs.
Unique All other alternative anti-skinning agents would require costly formulation changes.
Proven Performance Customer Approved Alkyd resin and paint producers in the European Union have fully tested and approved EZ-Blox® anti-skinning agent as a drop-in replacement for MEKO.
Market Validated Many paint producers have already launched decorative and wood coating products in the EU market utilising EZ-Blox® anti-skinning agent.
High Quality Anti-skinning performance and compatibility are equivalent to the highest standard MEKO; no other alternative can match these results.
